IMPROVEMENT IN MACHINES FOR MEASURING GRAIN.

Specification forming part of Letters Patent No. 39,980, dated'September l5, l1803.

To @ZZ whom, it may concern: l inV its lower end, said roller bearing upon the Be it known that I, THOMAS VILSON, of periphery of the cylinder G. i Metamora, in the county of IVoodford and To the periphery of the cylinder O, in line State of Illinois, have invented a new and Iinwith the roller G, there are attached two proproved Grain-Measuring Device; and I do ,jections, These projections are at oppohereby declare that the following` is a full, i site points on the cylinder, as shown clearly clear, and exact description of the same, refin Figs. 2 and 3. The slide F works undererence being had to the accompanying drawneath the discharge-orice ofthe hopper and ings, making a part of this specification, in I cuts off the discharge of grain therefrom at whichcertain times, as will be presently described.

To this bar It inder being provided with two receptacles, a there is attached a vertical rod, S, the upper a, the orifices of which are at opposite points end of which is bent or curved, and projects on the cylinder, as indicated in Fig. 3. This horizontally as shown at cx, over the cylinder cylinder is properly balanced on the shaft B O, to which, in line with ax, there are attached by means of a screw-rod, D, which passes two projectioiis,ss, of leather orotlier suitable transversely through the shaft B, and has material, said projections being placed at optwo weights, b, tted upon it at opposite sides posite points on the cylinder C. oftheshafi. Byadjustingthese weightsit will T is a lever, nicely balanced on its fnlcrnin t, be seen that the cylinder may be perfectly and having a notch, u', in its under side. balanced on its shaft B. The operation is as follows: Suppose the E is a hopper, which is placed in the upper cylinder O to be in such a position that one part of the box A, directly over the cylinder of its receptacles, a, will be under the dis- O, and F is a slide, which is attached to the. chargeaperture of the hopper E.. IYhen the Iower end otl an arm, c, the upper end of which cylinder is iii this position, the slide F will be is screwed to a shaft, d, having a rod, e, proout from the hopper in order to admit of the jecting from it, to the outer end of which a grain passing iiito the receptacle a, the slide vertical rod,]", is attached bya pivot, g. This F being moved out iii consequentie of one of rod f works ina guide, h, attached to theinner the projections 'i raising the roller Q, and side of the box A, and has a roller, G, fitted thereby actuating the slide. The grain falls into the receptacle a, and when a sufficient quantity is in said receptacle to throw the cylinder O out of balance, the cylinder will turn until one of the pinsj strikes the plate l, and if the requisite quantity oi' grain is in said receptacle the pin j will pass said plate I and move the scale-beam H. It' there is not sufticient grain in the receptacle to effect this, the cylinder will be retarded by the plate I, and Ithe ilow of the grain into the receptacle will be continued until the plate I is passed, it being understood that this preliminary movement of the cylinder does not admit ofthe orice of the receptacle passing out from underneath the hopper E. The cylinder turns until the grain is discharged from the receptacle d, and the other or empty receptacleis brought underneath the hopper E, the slide F closing when the projection i has passed from underneath it, so that the grain cannot pass from the hopper E until the empty receptacle d is underneath it, and the other projections raise the roller G and throw out the slide F. The two receptacles a ct are thus alternately iilled and discharged, and the revolutions ofthe cylinder O will be noted by the index .\l on the dial N and the index Q on the dial q. One dial may indicate bushels or units, and the other tens, hundreds, or thousands, according as the gear which operates the indexes is arranged. Each time the cylinder makes a half revolution its motion is retarded nea-r the completion ot' its movement in consequence ofthe cam i pressing upon the elastic bar R, and thereby drawing down the rod S, so that its upper horizontal end, a-X, will press down upon one of the projections s, and thereby retard the speed ot' the cylinder, so that the balance-lever T will catch over said projection and stop the cylinder, said lever otfering but as light resistance as but little is required. As each receptacle t becomes lled, or nearly so, the projections s readily escape from the lever to admit of the cylinder turning. Thus it will be seen that grain may be measured accurately by Weight and the number of bushels indicated at the end ofthe work or operation.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

l. rlhe cylinder C, provided with two grain receptacles, a a, in connection with the hopper E, provided with the slide F, operated through the medium of the roller G and projections i. z', substantially as and for the purpose herein set forth.

2. The scale-beam H, connected with the hinged plate I,in combination with the pins jj on the cylinder O, arranged to operate as and for the'purpose set forth.

3. The screw-rod D, passing through the cylinder-shaft B,and provided with the wei glits b b, for the purpose of balancing the cylinder O on the. shaft B, as specified.

4. The two indexes M Q, operated by gearing from the shaft B, substantially as shown, when said indexes and dials are used in combination With the cylinder C and scale-beam H, and all arranged for joint operation, as and for the purpose set forth.

5. The brake formed ot' the cani i on shaft B, the elastic rod R, rod S, curved or bent as shown, and the projections s s on the cylinder O, in combination with the lever or catch rI, all arranged to operate as set i'orth.
